Between 2012 and 2025, VIIRS detected fire in 139 km² of Styria at least once. In an average year it detected fire in 17 km², ranking 3rd of 9 regions of Austria.
Year by year
Detected area per year, km². Area of 0.01° cells with at least one detection in the year.
The busiest year was 2025, with 27 km² detected; the quietest was 2013, with 6.7 km². The 2021–2025 average is 44% higher than the 2012–2016 average.
Through the year
Share of all fire-days 2012–2025 by month. A fire-day is one cell with a detection on one day.
June, July and August together hold 53% of the fire-days in the record. The single busiest day was 20 April 2025, with detections in 10 cells.
Ground that burns again
Of the 139 km² with at least one detection, 11% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 115 | 83% |
| 2 years | 8.4 | 6.1% |
| 3 to 5 years | 8.4 | 6.1% |
| 6 to 10 years | 4.1 | 3.0% |
| 11 years or more | 3.3 | 2.4% |
The half-degree square with the most fire-days is centred at 47.25, 15.25 and holds 57% of the region's fire-days.

- How these figures are madeDetected area, cells, and the single-satellite record.
Detected area counts every 0.01° cell with at least one VIIRS detection, so a small fire counts as a whole cell and a fire missed by cloud or between passes is absent. Borders: Natural Earth 1:10m. 2012 begins on 20 January.
